Negus McClean murder: police offer £20,000 reward
Police are offering a £20,000 reward for information leading to the people who murdered a 15-year-old boy.
Negus McClean was stabbed in the chest and thigh in Westminster Road, Edmonton in north London, on 10 April this year.
Police believe he was chased by about seven youths on bicycles before he was attacked.
Detectives have arrested 12 people, aged between 16 and 20, in connection with murder. All of them have been released on police bail.
An appeal for information and witnesses, including a reconstruction and new CCTV footage, will be made on the BBC's Crimewatch programme at 2100 BST on Tuesday.
Det Ch Insp Stephen Clayman said: "I would urge anyone with information about the murder of Negus McClean to come forward and speak to my team.
"People may think that incidents such as Negus' murder are not their problem, but they have a devastating effect on family, friends and the community as a whole."
